I agree completely with the text I elided - the difficult bit of this  
kind of thing is walking the structure, dealing with sharing &  
circularities etc.  *However* that is generally code that the user is  
able to write without dependencies on the internals of the  
implementation (and indeed it's code that *only* they can write as it  
depends on their knowledge of what stuff counts for them).  I think  
the sizeof primitive is something reasonably important, because it's  
the bit you *can't* write without understanding the implementation.
